数值上，用matlab里vpa包手动提高数值精度就行了。
Significant efforts have been expended in the last decade to extend the QPE method to the non-Hermitian matrix11,12,13. As shown in a recent research14, QPE is extended to evaluate the eigenvalues of a non-Hermitian but diagonalizable matrix, which either only has real eigenvalues or the ...

matrix generationnon‐Hermitian matrixparallel computingspectrumIterative linear algebra methods to solve linear systems and eigenvalue problems with non〩ermitian matrices are important for both the simulation arising from diverse scientific fields and the applications related to big data, machine learning,...
We construct, analyze, and implement SSOR-like preconditioners for non-Hermitian positive definite system of linear equations when its coefficient matrix possesses either a dominant Hermitian part or a dominant skew-Hermitian part. We derive tight bounds for eigenvalues of the preconditioned matrices and...

A biorthonormal transfer-matrix renormalization-group (BTMRG) method for non-Hermitian matrices is presented. This BTMRG produces a dual set of biorthonormal bases to construct the renormalized transfer matrix with only half the dimensions of the matrix of a conventional transfer-matrix renormalization...
5) anti-sub-Hermite matrix 反次厄米特矩阵 1. We also characterize relationships among the sub-normal matrix,the sub-unitary matrix,the sub-Hermite matrix and the anti-sub-Hermite matrix. 主要研究了下列几方面问题:(i)次酉矩阵、次厄米特矩阵及反次厄米特矩阵的特征值与次特征值;(ii)次正规...
